3 Basic Information (General)
3.1 Intended use
The balance you purchased is intended to determine the weighing value of material
to be weighed. It is intended to be used as a “non-automatic balance”, i.e. the
material to be weighed is manually and carefully placed in the centre of the weighing
pan. As soon as a stable weighing value is reached the weighing value can be read.
3.2 Improper Use
Do not use balance for dynamic weighing. In the event that small quantities are
removed or added to the material to be weighed, incorrect weighing results can be
displayed due to the “stability compensation“. (Example: Slowly draining fluids from a
container on the balance.) Do not leave permanent load on the weighing pan. This
may damage the measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the balance,
minus a possibly existing tare load, must be strictly avoided. Balance may be
damage by this.
Never operate balance in explosive environment. The serial version is not explosion
protected.
The structure of the balance may not be modified. This may lead to incorrect
weighing results, safety-related faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.
3.3 Warranty
Warranty claims shall be voided in case
•Our conditions in the operation manual are ignored
•The appliance is used outside the described uses
•The appliance is modified or opened
•Mechanical damage or damage by media, liquids, natural wear and tear
•The appliance is improperly set up or incorrectly electrically connected
•The measuring system is overloaded
3.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the
balance and, if applicable, the testing weight, must be checked regularly. The
responsible user must define a suitable interval as well as type and scope of this
test. Information is available on KERN’s home page (www.kern-sohn.com with
regard to the monitoring of balance test substances and the test weights required for
this. In KERN's accredited DKD calibration laboratory test weights and balances may
be calibrated (return to the national standard) fast and at moderate cost.

4 Basic Safety Precautions
4.1 Pay attention to the instructions in the Operation Manual
Carefully read this operation manual before setup and commissioning,
even if you are already familiar with KERN balances.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transport and storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
5.2 Packaging / return transport
Keep all parts of the original packaging for a possibly
required return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove
loose/mobile parts.
Reattach possibly supplied transport securing devices.
Secure all parts such as the glass wind screen, the
weighing platform, power unit etc. against shifting and
damage.

6 Unpacking, Setup and Commissioning
6.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast, if you select the right location for your balance.
On the installation site observe the following:
•Place the balance on a firm, level surface;
•Avoid extreme heat as well as temperature fluctuation caused by installing
next to a radiator or in the direct sunlight;
•Protect the balance against direct draughts due to open windows and doors;
•Avoid jarring during weighing;
•Protect the balance against high humidity, vapours and dust;
•Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (condensation of air humidity on the appliance)
may occur if a cold appliance is taken to a considerably warmer environment.
In this case, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
•Avoid static charge of goods to be weighed or weighing container.
If electro-magnetic fields or static charge occur, or if the power supply is unstable
major deviations on the display (incorrect weighing results) are possible. In that case,
the location must be changed.
6.2 Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.

RIB-BA-e-1610 15
6.2.1 Placing
Level balance with foot screws until the air bubble of the
water balance is in the prescribed circle.
6.2.2 Scope of delivery / serial accessories:
•Balance, see chap. 2
•Mains adapter
•Protective cover
•Operating instructions
•Tripod (only for H models)
6.3 Mains connection
Power is supplied via the external mains adapter. The stated voltage value must be
the same as the local voltage.
Only use KERN original mains adapter. Using other makes requires consent by
KERN.
6.4 Storage battery operation (optional)
The optionally supplied battery is charged with the supplied power supply.
Before the first use, the battery should be charged by connecting it to the mains
power supply for at least 14 hours.
•The appearance of the battery symbol in the display windows indicates
that the battery is almost exhausted. Charge the battery with the help of the
supplied power pack.

6.5 Assembly of tripod (only H models)
Connection cable
- on the balance - and on the tripod
Fix the tripod on the balance as described below:
Loosen the side screws from the tripod
holder of the balance
Plug together the both connections.
Ensure that the cables are not twisted.

RIB-BA-e-1610 17
Plug the tripod carefully into the tripod
holder of the balance.
Ensure that the cables are not
squeezed.
Align the display on the tripod towards
the customer (see. fig. below).
Fix the tripod using the two side screws
of the tripod holder.
Switch on the balance and check if the
tripod display works.
Should this not be the case, detach the
tripod from the balance and check the
connections.

6.6 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. During this warming
up time the balance must be connected to the power supply (mains, accumulator).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
6.7 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated - in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location
(only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To
receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
The adjustment is locked for verified balances. Carrying out adjustment
requires that the seal is destroyed and the adjusting switch is confirmed in
step 3 when turning on the scale. For position of adjusting switch, see chap.
6.8.1
Attention:
After destruction of the seal the balance must be re-verified by an
authorised agency and a new verification wire/seal mark fitted before it can
be reused for applications subject to verification.

RIB-BA-e-1610 19
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization. Ensure that there are no objects on the weighing pan.
Arrange adjustment weight, details see chap.1 „Technical data“
In weighing mode press
and keep pressed; additionally
press .
If „CAL oFF“ appears in the window of the basic price or if the balance
does not react, the verification switch on the lower side of the balance
must be set to position „ON“, see chap. 6.8.1
The value of the adjustment
weight appears.
The first digit is flashing.
Either
- Take over the
displayed
adjustment weight,
or
- use the numeric
keys to enter a
new adjustment
weight
Put adjustment weight in the
centre of the weighing plate
and confirm by

20 RIB-BA-e-1610
„--------“ will be displayed
shortly, the balance will be
adjusted and after that
changes automatically into
weighing mode.
The weight value of the
adjustment weight on the
weighing plate will be
displayed.
Now the process of
adjustment has been finished
successfully.
In case of an adjustment error or incorrect adjusting weight the display will
show an error message; repeat adjustment process.
